How to prevent water pollution engineering machinery hydraulic system are discussed in this paper, how to control construction of hydropower construction equipment of hydraulic system from pollution, raise the utilization of construction equipment, to ensure readiness, safe and reliable operation of construction equipment and improve the economic benefit. Keywords: equipment for hydraulic system of hydropower construction enterprise, the pollution in the field of construction machinery long-term high workload, easy cause many faults, hydraulic system failure multiple parts is, according to the statistics, engineering machinery and hydraulic system failure is about 70 percent of the system caused by pollution. Hydraulic system directly affect the service life of equipment and mechanical engineering construction, how to effectively control system to ensure the engineering machinery is pollution, safe and reliable operation and improve the economic benefit of the key. Based on the construction of guangxi baise project as an example, the equipment used to control the hydraulic system of the contaminated simple analysis. 1 and in maintenance process control pollutants into the hydraulic system of the pollutants in hydraulic system of 1.1 (1) physical form solid metal cutting: the main pollutants, burr, silica sand, abrasive, welding slag, rust, additives and dirt and other solids. (2) liquid pollutants commonly: including does not conform to the requirements of oil, water system, coating and chlorine and halide etc. (3) is mainly gaseous contaminants: the air with system. 1.2 hydraulic system sources of air pollutants and control 1.2.1 non-chip-producing condition of pollution produced mainly has: the system already exists in the use of pollution, before is mainly due to the hydraulic components, such as oil pipeline, the new factory is not strictly control pollution index before, the pollution of congenital conditions, only for the hydraulic oil filter, such as strengthening inspection blooms that pollutants, replace filter pistil and hydraulic oil. Given control maintenance process pollutants into (1) in the baise project department, established hydraulic system maintenance, isolation and 20.08 20.08 alone with mechanical processing or benchwork spaced, absolutely forbidden in open-air, shed, sundry or warehouse decomposition and assembling hydraulic parts. To ensure the hydraulic parts disassembling and cleaning in accord with national standards for clean room, prevent air and dust pollution. Operators enter repair shop should wear the uniform fiber is working cap, and prevent fiber, dust, hair, dander, etc in hydraulic system were caused by man-made pollution, smoking is prohibited in sticky, eating. (2) improve maintenance staff awareness, avoid the refueling, replacement or cleaning devices for operation level and poor conditions or into the pollutant, hydraulic components assembly process, should adopt "stem assembly method, namely after cleaning parts, in order not to make cleaning and surface in parts of assembly quality, should be in parts surface drying after assembling, When the assembly to wear gloves to wipe fiber fabrics with mounting surface, prevent dirt into components inside fiber, After the assembly has not hydraulic components, components, and shall assemble at all of them with plastic stopper oil mouths, loop when installed, hose pipe must pass pickling, rinse clean compressed air with clean, before receiving actuators, if remove hose, midway through timely bind good hose-connect, joint body before installation, also want to use kerosene clean, dry and clean compressed air, (3) hydraulic components cleaning before the new hydraulic parts assembly, the old hydraulic parts must be contaminated by cleaning after cleaning process can be used, should do the following: (1) only permitted use kerosene, cleaning and hydraulic system of gasoline and work with the same brand of hydraulic oil, 2 in special hydraulic pressure cleaning should be cleaned on, to ensure the purity of the temporary table, 3 after cleaning parts to cotton, hemp, silk and chemical fiber cloth to wipe, prevent loss of fiber pollution system, nor to skin the tiger tiger parts drum wind (skin with dust particles) internal may, when necessary, use of dry clean compressed air is blown dry parts, After cleaning the parts (not directly on the ground, benchwork assembly work platform, and should take cover in the container and infuse the hydraulic oil, 5 but not already cleaned assembly parts should be put in the temporary preservation, wet areas should pay attention to rust. 130 promptly replace hydraulic oil cylinder of components dustproof circle replace hydraulic cylinder of components, avoid dust outside pollutants as components of the movement, these particles into the grain, and assembly of sand casting off such internal particles will abrade components, surface and generate more new particle pollution, timely change is to avoid pollution of these particles into the best method of hydraulic system.
